:1,3,13,39,169,507
Now, list down the factors of 840
:1,2,3,4,5,6,7,8,10,12,14,15,20,21,24,28,30,35,40,42,56,60,70,84,105,120,140,168,210,280,420,840
Greatest Common Factor
We found the factors 507,840 . The biggest common factor number is the GCF number.
So the greatest common factor 507,840 is 3.
Lets's calculate LCM of 30,4342
2 | 30, 4342 |
15, 2171 |
∴ So the LCM of the given numbers is 2 x 15 x 2171 = 65130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/65130
Therefore, the GCF of Fractions 507/30,840/4342 is 3/65130
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 30,4342 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,4342) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(30,4342) x common factors =2 x 1 = 2
LCM(30,4342) = ( 30 × 4342 ) / 2
LCM(30,4342) = 130260 / 2
LCM(30,4342) = 65130
